Is Antifreeze (Ethylene Glycol) Toxic to Dogs?
Emergency🚨 Dangerous — act now
Ethylene glycol is the poison vets dread: dogs lap it willingly from driveway puddles, early signs mimic drunkenness and then deceptively improve, while metabolites silently crystallize the kidneys. By the time kidney failure shows (36–72h), it's often too late — but treated within the first few hours, the antidote is highly effective. There is no 'wait and see' with antifreeze.
What makes it dangerous: Ethylene glycol → calcium oxalate crystal kidney destruction
Symptoms to watch for
- Stumbling, 'drunk' behavior (30min–12h)
- Excessive thirst and urination
- Vomiting
- Apparent recovery, then collapse
- Kidney failure (1–3 days)
What to do right now
- Go to an emergency vet NOW — minutes count, don't call around first
- If you saw the puddle, note the product; pet-safer propylene glycol coolants exist but assume the worst
- Clean any garage/driveway spills immediately (before dogs find them)

Be ready before the next emergency
The worst time to go looking for supplies is at 2am with a sick dog. Keeping these three things in one box saves the ten minutes that actually matter.
Pet First Aid Kit
A pre-packed kit with gauze, saline flush, tweezers, a tick remover and a foil blanket in one grab-and-go bag.
Everything you'd otherwise be hunting for while your dog is deteriorating
Veterinary Digital Thermometer
Lets you give the vet or hotline a real temperature over the phone instead of guessing — which often decides whether you're told to come in.
A healthy dog runs 101–102.5°F; outside that range changes the advice
Soft Mesh Dog Muzzle
A dog in pain or panic may snap at the person handling them, even a devoted owner. Vets keep one in every home kit for exactly this.
